LEWIS WILLIAMS, OF JOHNSTOVVN, PENNSYLVANIA, ASSIGNOB TO CAMBRIA IRONCOMPANY, OF SAME PLACE.

APPARATUS FOR ANNEALING WIRE.

SPECIFICATION forming part of Letters Patent No. 312,417, dated February17,1885.

Application filed August 24, 1883. (No model.)

To (LZZ whom it may concern-.-

Be it known that I, LEWIS WILLIAMS, a citizen of the United States,residing at-Johnstown, in the county of Gambria and State ofPennsylvania, haveinvented certain new and useful Improvements inApparatus for Annealing \Vire, of which the following isafnll, clear,and exact description.

In the drawings, Figure l is a section through an annealing pot or oven,showing my improvements; and Fig. 2 is a top View of the same. 7

The parts, of the oven are indicated as follows: a is the brick-work ormasonry. d is the annealing-pot. b is a fire-arch. c c are tines leadingfrom the fire-arch to space around the pot. h h are floor-platescovering the masonry. f is the cover of the annealing-pot. g is aholethrough the cover. t is a plate covering the chargi ng-holein thefloor-plates, provided with an orifice, p. k is a flue secured to coveri, the continuation of which flue, n, is secured to the floor-plate h,the further continuance of this flue to connect with a general draftflue or chimney being indicated by 0. 1" being a hole through thefloor-plates. m is a peep-ho1e through which to ascertain the con ditionof the wire, and Zis a ringby which the covering-plate i and itsattached flue are handled.

Theoperation of this apparatus is as follows: The coveringsz' and fbeing removed,

the pot d is filled with wire and covered with the lid f. Theplate-covering z, with its attached flue 7c, is placed in position,covering the hole in the floorplates, conneczion being made between theparts of the line It and a by inserting the one into the other, orotherwise. This allows the heat and smoke to pass around theanuealingpot,and thence through the lines is, a, and 0 to the generalflue or chimney.

It will be found convenient in practice to connect the fine 0 leadingfrom each pot with a general fine passing along or between a row or rowsof ovens and leading into a chimney.

The plate 2', with its attached fine 7c, are strongly made of iron, anda crane may be conveniently used in shifting them.

I am aware that an annealing-furnace has been constructed withcovering-plate and fines, as these are essential parts in certain formsof ovens, and that gases have been taken off centrally through thecovering-plate; but my apparatus differs in making the flue 7c fast uponthe covering-plate i and removable with it, and connecting removablefine k with permanent flue n. This construction prevents the escape ofgases, which is always disagreeable and deleterious; it gives solidityto the covering. and enables it to be manipulated wit-h facility, and animproved draft is a result.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In combination with an annealing-ovemthe covering-plate if, the flue It,permanently attached thereto, the elbow a,- and downwardacting flue 0,substantially as and for the purpose set forth.
